The percentage of methane gases emissions according to the various research studies is around 25% of the total emission gases of the waste materials. For all industrialized nations, food waste costs approximately $680 billion/year. The dramatic increase in population and the waste of organic and non-organic materials lead to the use of biomass energy as the source of the renewable energy system to produce a natural gas (N.G.), which can be utilized in cooking or commercialized for the public. The burn out of the waste and the garbage materials causes tremendous pollution and global warming;however, utilizing the Biogas Digest System (BDS) will stop polluting the surrounding environment. The amount of natural gases production was measured for various atmospheric conditions. The important findings of this study are the amount of N.G., which can be increased by mixing two different types of organic waste materials.展开更多

The research aims to study, develop and design such types of facilities in an environmentally sensitive manner, using local materials or recycled materials, with a design that serves the environment and is consistent with the nature and cultural background of the place, through Energy Efficiency and Renewable Energies. This leads us to the ideas and foundations of seeking to preserve natural energy, respect the environment and reduce the impact of construction thereon. The research applies environmental and sustainable design standards to a proposed model designed by the Author for desert lodges, and the most important advantages of supporting ecotourism, by observing the principles of good design consistent with the local environment and culture, preventing the use of internal pollution sources, adapting to the climate, using alternative environmentally friendly materials, the efficiency of production and use of energy to promote the use of clean renewable energy. As important elements in the development of tourism and to help to preserve natural heritage and biodiversity. Such architectural solutions aim to achieve the objectives of eco-design, in terms of reducing the cost of energy in buildings, using natural energy instead of mechanical power systems, in addition to creating a healthy and comfortable environment.展开更多
